Windows 2008 R2 - AS/400

We have a network with a SBS2008 server, while Windows2008R2 and Windows2003 servers in the domain. Besides running the network in an AS/400 system.

The AD and the AS/400 are created the same user names and passwords.

Now we want Win2008R2 systems directly from an open folder on the AS/400. This works perfectly from the Windows2003 system, but from the Windows2008R2 system and also from Windows 7 systems this will not work. We have after research on the Internet already changed some settings on the Windows systems, but without effect:

- UAC is disabled
- NoLMHash = 0
- LMCompatibilityLevel = 0

On the AS/400, the following setting:

If we WIN2008R2 from a folder on the AS/400 system, the Open, we get a login screen. If we correct this login screen, enter username and password, we can open the folder. However on the Win2003 system, this works without us having to fill in this information.

In Trace we have seen that the stiff Win2008R2 systems keep sending the passwords in NTLMv2 format.

Could you tell us what settings to get it done WIN2008R2 servers also from the folder to open directly.

If you have an IBM Support User ID that entitles you to access protected support content, you can check out this support article:

Windows XP Prompts Repeatedly for a User ID When Mapping a Drive┬┐                         

This document explains why Microsoft Windows  Me/NT/2000/XP and above using NT LAN Manager Version 2 (NTLMv2)  challenge/response authentication may prompt repeatedly for an operating  system user ID and password. Although this is a Windows operating  system issue, suggestions are provided that may be helpful in resolving  the authentication issues.┬┐

Otherwise, here are some things to check:

What OS version are you running on the AS/400?  Verify that you are on a compatible iOS release and that all of the approproate PTF's are applied:

Review this IBM Support document for Windows 7, since some of these issues apply to Win2008 as well:
